Rare uterine serosal pregnancy after in vitro fertilization in a woman with bilateral salpingectomy

Objective:To improve the understanding of ectopic pregnancy after bilateral salpingectomy through case analysis and literature review.Method:A case of uterine serosal pregnancy after in vitro fertilization and embryo transfer(IVF-ET)in a woman with bilateral salpingectomy was reported in detail and summarized,and relevant literatures searched in Pubmed were analyzed.Results:The patient had a sudden abdominal pain 18 days after transplantation.Ultrasound showed no pregnancy sac in the intrauterine cavity and bilateral adnexal areas,but there was a large amount of fluid in the Pouch of Douglas,which was an indication for surgical exploration.During the operation,the pregnancy tissue was found on the uterine serosal and cleared in time.And the patient recovered well after surgery.Review of the literatures showed that most of ectopic pregnancies after bilateral salpingectomy were treated surgically and had a good prognosis.Conclusion:Ectopic pregnancy after bilateral salpingectomy is extremely rare and should be early judged by the patients’signs.Surgical treatment timely can achieve good outcome.
